Abstract
The invention provides an electro-optical device capable of improving a high light projection efficiency to the outside while maintaining sealing ability for providing high recognition of vision. An organic electroluminescence display can include a light permeable substrate, and an organic electroluminescence element having a luminous layer and positive hole transfer layer interposed between a pair of electrodes. Additionally, a low refractivity film having a lower refractivity than the substrate, and a seal layer for blocking the air from invading from the substrate side to the organic electroluminescence element are laminated between the substrate and electrode of the organic electroluminescence element.

An electro-optical device having a luminous element, comprising:
- a luminous layer;
- a low refractivity film disposed above a substrate in a direction for projecting a light emitted from the luminous layera seal layer disposed above the substrate.
An electro-optical device, comprising:
- a luminous element, wherein a low refractivity film in which at least one of a drying agent and an adsorbent is dispersed is disposed in a direction for projecting a light emitted from the luminous element.
A film member, comprising a low refractivity film and a seal layer that suppresses substances from permeating.
A laminated film, comprising a low refractivity film and a seal layer that suppresses substances from permeating.
A low refractivity film, comprising at least one of a drying agent and an adsorbent dispersed in the low refractivity material.
An electro-optical device, comprising:
- an electro-optical element and at least one of the film member having a low refractivity film and a seal layer that suppresses substances from permeating;
- the laminated film having a low refractivity film and a seal layer that suppresses substances from permeating;
- the low refractivity film having at least one of a drying agent and an adsorbent dispersed in the low refractivity material;
- and the laminated multilayer film comprising the low refractivity film including at least one of a drying agent and an absorbent dispersed in the low refractivity material.
